A singularity free classical theory of gravity
Saurya Das, Mitja Fridman, Sourav Sur
We present a classical theory of gravity, which is singularity free at short distances and reduces to General Relativity at large distances. We discuss its implications.

Varying Newton's constant: a cure for gravitational maladies?
Saurya Das, Sourav Sur
We show that a slowly varying Newton's constant, consistent with existing bounds, can potentially explain a host of observations pertaining to gravitational effects or phenomena ac…

Feasibility analysis of a proposed test of quantum gravity via novel optical magnetometry in xenon
James Maldaner, Mitja Fridman, Saurya Das +1
We present an analysis of the sensitivity limits of a proposed experimental search for quantum gravity, using a novel approach based on optical magnetometry in the noble gas isotop…
